Open-source Windows and Office activator featuring HWID, Ohook, TSforge, and Online KMS activation methods, along with advanced troubleshooting.
## How to Activate Windows / Office / Extended Security Updates (ESU)?
### Method 1 - PowerShell ❤️
1. Click the **Start Menu**, type `PowerShell`, and open it.
2. Copy and paste the code below and press **Enter.**
- For **Windows 8.1, 10 and 11**:
```
irm https://get.activated.win | iex
```
If the above is blocked (by ISP/DNS), try this (needs updated Windows 10 or 11):
```
iex (curl.exe -s --doh-url https://1.1.1.1/dns-query https://get.activated.win | Out-String)
```
- **Script not launching? Use the below-listed Method 2.**
3. In the menu that appears, type the number corresponding to one of the **Green** options.

### Method 2 - Traditional (Windows Vista and later)

* [**MAS_AIO.zip**](https://dev.azure.com/massgrave/Microsoft-Activation-Scripts/_apis/git/repositories/Microsoft-Activation-Scripts/items?$format=zip) (If the direct script is blocked by your browser)

> [!TIP]
> - Some ISPs/DNS providers block access to our domains. You can bypass this by enabling [DNS-over-HTTPS (DoH)](https://developers.cloudflare.com/1.1.1.1/encryption/dns-over-https/encrypted-dns-browsers/) in your browser.
> - **Having trouble**? Visit our [troubleshooting page](https://massgrave.dev/troubleshoot) or raise an issue on [GitHub](https://github.com/massgravel/Microsoft-Activation-Scripts/issues).
> [!NOTE]
>
> - The `irm` command in PowerShell downloads a script from a specified URL, and the `iex` command executes it.
> - Always double-check the URL before executing the command and verify the source is trustworthy when manually downloading files.
> - Be cautious of third parties spreading malware disguised as MAS by altering the URL in the PowerShell command.
